Carbon has by definition 6 protons. However, its many isotopes can have anywhere from 2 neutrons to 16 neutrons, with 6 neutrons being the most common (~95% of all carbon). Carbon has by definition <b>6 protons</b>.
(a) Carbon has three isotopes with different numbers of neutrons: carbon 12 (C12, 6 protons + 6 neutrons), carbon 13 (C13, 6 protons + 7 neutrons), and carbon 14 (C14, 6 protons + 8 neutrons). C12 and C13 are stable. The atomic nucleus in C14 is unstable making the isotope radioactive.
